6 Claims.

This invention relates to calculations and has for an object to provide in such a device a ready means for handicapping racing dogson the basis of their past performances, whereby the several factors. entering into the computation,

such asthe number of races won, the number of from the following description of it taken in conjunction with the accompanying drawing, in which 7 Fig. 1 is a plan view of the calculator and Fig. 2 is a cross section on the line 2-2 of Referring to the drawing, I is a square baseplate, made of suitable material, such as cardboard or Celluloid, upon which may be printed or engraved the annular dlal H composed of a series of index points I2, numbered consecutively from zero to 35, disposed equidistant arcuately about a portion of the margin of said dial II, except that the zero point is removed four points from the index point associated with the number ((1.1) V V i V concentrically and rotatably mounted on a center Dost, I3 extending through the center of the annular dial I I is a circular dial I4 composed of a thin sheet of Celluloid having the same diameter as thatof the inner periphery of the annular dial II and provided along its peripheral'margin with a series of index points I5, likewise numbered consecutively from zero to 35' but running in the opposite direction to the numbers on the dial I I and without any intervening spaced points between the zero and the number 1. y The arcuate spacing of the numbered points I5 is the same as "that of the points I2 so that they may bev brought into'radial alinement with each other. A third circular dial I6 is rotatably mounted on the center 'post- I3 in superimposed relation to the dials 'I I and I4 and i provided about the greater portion of its peripheral margin with a series of numbers I1 running from zero, by even numbers; to "126, and in the same direction as the numbered points I5 on the dial I4; and are also similarly arcuately spaced. The diameter of the dial I6 is sufficiently-smaller than that of the dial to expose to view the numbered points I5. Positioned intermediate the zero and the a portion of the circumference of said disc over the said dial I I, I4 and IS, with its side edges diverging, to the edge of the base plate I0 where 'it is securely fastened, thus holding the rotatable dials I4 and I6 in substantially the same plane with the dial II and preventing any tendency of them to curl up.

Cut out windows 29 and 2| are formed in said bridging member in register with the numbers I! on the dial I'd. The window 20 is of suflicient size to disclose to View simultaneously any adjoiningtwo of said numbers I! while the window 2| is spaced therefrom a distance equal to the spacing of two of the numbers I! and is of a size sufficient to disclose to View only one of said numbers.

The center post I3 is provided with headed portions 22 and 23 between which are held the base plate Ii), the rotatable dials I4 and IB and the bridging member I9 as tightly together as is consistent with the free rotatability of the dials I4 and I6. A sheet 24 of pasteboard or the like serves to cover the bottom of the base plate I I and the head 22 of the center post I3, and a U-shaped strip of cardboard 25 extending around the base plate I0 serves to bind the outer end of the bridging memberIS thereto.

While I have mentioned cardboard or Celluloid as the materials out of which the various parts of the device may be made, it is obvious that thin metal or any other suitable material may be used instead.

From the foregoing description it will be seen that I have provided a simple and compact demay be considered the winning of a race for the purpose of this invention. The operator of ;consecutiv dic-ating the umber of in :a selected bers onsaid first dial b? t the device rotates the dial is until thepoint numbered 12 thereon comes into register with the point numbered 12 on the dial H. Then holding said dial it in that position he rotates the dial iii until the'pointer'i8 comes into position opposite the number 23;and that racing dogs comparative rating isshown in the windows 29 and 2|.
